SPECIFICATION forming part ofuLetterslPatent No.V 605,163, dated J' une 7, 1898.` Appiimioniifnajs,1895. `sar-a11t.15,4'.9`,76e,` (N omodelo TOaZZ whom t may concern,.-

Be it known that I,BYR0N BENJAMINy GOLD- SMITH, a citizen of theUnited States, and a resident of New York, in the county and State of New York, have invented 'certain new and useful Improvements in Erasers, ofl which the following is a specification."

My vinvention has reference "to" improvements in pencil and ink erasers adapted for general and independent use, but more particularly usefulin connection with lead-pencils; .and its object is to provide an eraser whereby the usek of glue or vcement for holding the erasing material (generally rubber) in its support is avoided, whereby'the erasing material is utilized to greater advantage and at the same time is so held that accidental extraction from the holder'is'prevented.

An eraser constructed Vin accordance'i with this invention is composed of a sleeve orferi' rule having onejendcontracted inany` inan-V ner, but preferably so as to be tapering or conical, and having a block of erasing matel rial, .provided with a head or enlargement,

vand inwiiiein-v 3 confined in the contracted'end of the ferrule in such mannenthatthe erasing-block is exthe front end of,"thfefferrule,fl and that it can only be removed through the rear end,`through which it was introduced, by the application of considerable force.`

If the eraser is' intended for independent use, the accidental extraction of the erasingblock through the rear end of the .ferruleis prevented by an interior ledgewithin the ferrule end or by a block of wood orsimilar material. 1f the eraser is to be used'as'an adjunct to a lead-pencil, then the lead-pencil itself mayperform the function of such block or ledge. l Allfthais will more yfully appear from the follovvingdetail.v descriptiongtaken in connection ,with the''ac'eompanying drawings,'whicih`gform' a part of this specification,

flis 'an enlarged` longitudinalgsection, partly in elevation, of the improved eraser as applied to a lead-pencil. Figl`2 is a perspective view ofanother form Qof' the improvd'eraser'when used as an adjunct to Figui'y gitudinal section",r partlyiin elevation, of a third form ofthe improvement. Fig. 4 is a lperspective viewof the improved eraser combiried with a brush. Fig. 5 is a longitudinal section thereof. Fig. 6 is a longitudinal secin'accordance with the invention. Fig. 7 is a side view of the improved eraser adapted to serve as a-point-protector for a lead-pencil. gFig, 8 is afplan view, with parts broken away, z Of myimproved eraser adapted for independent use. Fig. 9 is a section of the same on of another form of independent eraser.

Like-numerals of reference indicate like parts.

Referring now particularly to Fig. l, the sleeveV or ferrule l, which constitutes the holder for the erasing-block 2, is contracted rearfofthe taper thus formed there is in the outer surface lof the sleeve a depression or groove 4, passing yall around the sleeve and forming in the interior a corresponding bead or ledge 5.d The erasing-block 2 is of practically uniform thickness throughout the greater portion of its length, but has at its rear end a tapering head 6, conforming in size and shape tothe 'taper 8 of the forward end of the sleeve.

The erasing-block is inserted into the holdersleeve through the 'contracted open end of the same, with the uniform portion of the block toward the tapering end of the sleeve, through whichend that uniform portion of the block is projected. Then the head 6 is forced past the ledge 5, and the block is thus confined between the taper 3 of the sleeve and the ledge 5,*so`that `it can neither be extracted Yfrom the sleeve forwardly ,non pushed back by the pressure ordinarily exertedin the use of theieraser. Y I Y erasing-block is Vof Athe properxsi'z'gitwill b e so tightly held between the nozzle ofthe sleeve andthe ledge behind the sarnelthat'i't'liiot beloosened by the bending 'andshalirig 'to which igt-is subjected in the ordinary manipulation'of YJche device. l It Will be seen `.that only'avery small portion of the eraser-block is confined in the sleeve and thatby'ffar'the greaterportion of it projects beyondthe saine in'positzionfor use. Thus a great savingin erasingmaterial is secured as compared with erasers heretofore made, where the greater tion of'a combined pencil and ink eraser made' vat its forward end 3, and immediately in the the line oom'of FiglS, and Fig. lO is a view lf .the taperingwheadof the IOO portion of the erasing material was held in the sleeve in order to prevent as much as possible its pulling out orloosening in the holder; but notwithstanding the great waste of erasing material necessitated by these old constructions the erasing-block would frequently become loose in the holder and eventually drop out.

In Fig. 1 the eraser is shown as an attachment to a lead-pencil 7, over which the sleeve 1 is slipped as a ferrule, and while this special use of the improved eraser offers particular advantages I am byno means confined to that use, since the eraser may be used independently of lead-pencils, as will be readily understood and as will more particularly appear farther on.

In Fig. 1 the erasing-block is supposed to be cylindrical 3 but it may be prismatic, as shown in the perspective view in Fig. 2, in which case the nozzle will have llat pyramidal faces 3', as indicated.

Then the improved eraser is used as an attaehment to lead-pencils, its construction may be slightly simplified, as shown in Fig. 3. In this case the groove land corresponding ledge 5 may be omitted from the sleeve, since the body of the pencil 7 would assume the function of the ledge.

As an independent structure the whole body of the eraser may be prismatic, as shown in Figs. 4, 5, and (i. Figs. 4 and 5 illustrate an eraser of this kind combined with a brush. The eraser proper is shown exactly as in the preceding ligures of drawings, and particularly as in Fig. 2, except that the sleeve 1 is here shown prismatic; but in all other respects the construction is the same. The brush-holder is a simple prismatic tube with slots J in its sides, so that it may be easily slipped into and out of the sleeve 1. The brush 10 for removing the abraded particles of paper and erasing material is glued or otherwise secured in the tube 8.

In Fig. (3 there are shown two erasers with their sleeves 1 1 telcscoping; but otherwise the construction is the same as that shown in Figs. fand 5. Ordinarily one of the erasingbloclis 2 will be soft for erasing pencil-marks and the other 2 will be hard and somewhat gritty for erasing ink-marks.

In Fig. 7 the sleeve 1 is shown composed of two semicylindrical parts 1 and 12, held together by a ring 11, but in other respects is similar to the form shown in Fig. 1. This form of the eraser-holder is so constructed that it may be slipped upon the butt-end of a pencil, but grips the same with'suffieient friction to remain in place when the eraser is in use. It may also be removed from the butt-end of the pencil and slipped onto the sharpened end thereof, and thereby act as a point-protector.

In Figs. 8, 9, and 10 there is shown an independent eraser having three equidistant radial blocks 2 of erasive material projecting from a llat hexagonal case 12. Three side walls of the case 12 are cut away, andthe remaining sides 13 form with the same three equidistant tapering nozzles for the erasingblocks 2. The case l2 is formed of two like parts held together by a rivet or bolt 1 l-, as indicated in Fig. 0.

In the form shown in Figs. S and i) the erasing-blocks 2 are held against rearward movement by a hexagonal block 15 of wood or other material within the case, and in the form shown in Fig. 10 the grooves-l, forming corresponding inwardly -projeeting ledges, perform the same function as the block 15.

It will be observed that the forms of independent eraser shown in Figs. 8, 9, and 10 are in effect but a multiplication ofthe form shown in Fig. 7.

It will be readily understood that numerous other variations of the details of construction may be made Without departing from myinvention, and I am therefore not limited to the identical features herein shown and described.

Having now fully described my invention, I claim and desire to secure by Letters latent- 1. A pencil or ink eraser composed of a holder having a tapering, contracted nozzle and ablock of erasing material with a body portion of such size as to pass freely through the mouth of the nozzle, and ahead or enlargement conforming in shape to the tapered nozzle and too large to pass through the mouth thereof, substantially as described.

2. A pencil or inl: eraser composed of a holder having a contracted nozzle andan inwardly-proj ectiu g ledge behind the same, and a block of erasing material having a body portion of such size as to pass freely through the mouth of the nozzle and formed with a head conforming to the nozzle and too large to pass through the mouth thereof, and engaging the ledge, substantially as described.
